Looks grand. Nice and big/healthy. Just some marco nute, (immobile nute), it's just not enough core NPK+CAL in the Sub and new growth is sucking what it needs from the old fan leafs stores. Could do with an increase in NPK+CAL and with her bring an auto you are using a micro nute right? Increase PK/BLOOM and maybe stick her on 1/3 of grow nutes unless your brand says not to mix grow/bloom together, as I can't mix mine. Good luck.
